Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 5.4.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. Install-time code refreshes existing Todoist CLI skill files in supported coding-agent locations. This is a first-party agent-extension lifecycle mutation, not a confirmed hostile attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-29T00:49:58.567Z - **Finished:** 2026-09-29T00:50:49.556Z - **Download time:** 1006 ms - **Static scan time:** 1310 ms - **AI review time:** 48672 ms - **Total time:** 50989 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Install-time code refreshes existing Todoist CLI skill files in supported coding-agent locations. This is a first-party agent-extension lifecycle mutation, not a confirmed hostile attack. - **Trigger:** npm postinstall runs when the package is installed or updated. - **Impact:** Existing agent instructions can change automatically during package installation; no credential exfiltration or remote payload execution was confirmed. - **Evidence paths:** dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/create-installer.js, dist/lib/skills/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-29T00:50:49.556Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle entry calls the installed-skill updater, which detects existing skills and writes regenerated content to their configured paths. - **Rationale:** Automatic postinstall rewriting of installed agent skills is a concrete guarded extension-lifecycle risk. The inspected source does not establish malicious intent or a separate active attack. - **Files touched:** dist/postinstall.js, dist/lib/skills/update-installed.js, dist/lib/skills/create-installer.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package declares a postinstall lifecycle hook., The postinstall entry automatically updates previously installed agent skills., The updater rewrites each detected installed or legacy skill., Skill installers target coding-agent directories including Claude Code, Codex, and Copilot., Installer updates create directories and write skill files. - **Evidence against:** The update path only acts when a package-specific skill is already detected., No child-process, eval, or unrelated network endpoint was found in the inspected lifecycle path. ## Affected versions and remediation This report applies to @doist/todoist-cli@5.4.3. - Review the evidence and your use of @doist/todoist-cli@5.4.3 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
